Need someone to write a gauge app

So there are 2 programs that I'm currently using to display all of my gauges. Both of them display exclusive info; the software for my coolingmist smart injection controller displays EGT, water injection flow, and air temp, and the other displays data from my piggyback (turboxs UTEC). Both are connected via serial cables. I want to consolidate the readings from both units and display them in a small window on Road Runner so that I can see them on every page when I navigate through music and other things, like this.
I'm willing to pay someone to do all of this for me, but I don't know where to start and how much I can expect to pay. Any help will be greatly appreciated.
